Sigilstar, called the "crossroads of Thrane", is named after Eberron's pole star, because the rest of Thrane is centered on the small city as the skies of Eberron are centered on that star. It sits astride the Lightning Rail line between Aruldusk and Flamekeep, and on the Orien trade road between the southern and northern parts of the nation of Thrane. Its position on the northern bank of the Thrane River allows it access via waterway to Scion's Sound as well. The city is the primary transfer point for cargo that is switching modes of transport between land, water and rail.
